Materials Data on HgGe3 by Materials Project

HgGe3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Hg is bonded to twelve equivalent Ge atoms to form a mixture of face and corner-sharing HgGe12 cuboctahedra. There are six shorter (3.13 Å) and six longer (3.14 Å) Hg–Ge bond lengths. Ge is bonded in a 10-coordinate geometry to four equivalent Hg and six equivalent Ge atoms. There are two shorter (3.02 Å) and four longer (3.07 Å) Ge–Ge bond lengths.

Materials Data on HgGe3 by Materials Project

HgGe3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Hg is bonded to twelve equivalent Ge atoms to form HgGe12 cuboctahedra that share corners with twelve equivalent HgGe12 cuboctahedra, edges with twenty-four equivalent GeHg4Ge8 cuboctahedra, faces with six equivalent HgGe12 cuboctahedra, and faces with twelve equivalent GeHg4Ge8 cuboctahedra. All Hg–Ge bond lengths are 3.11 Å. Ge is bonded to four equivalent Hg and eight equivalent Ge atoms to form GeHg4Ge8 cuboctahedra that share corners with twelve equivalent GeHg4Ge8 cuboctahedra, edges with eight equivalent HgGe12 cuboctahedra, edges with sixteen equivalent GeHg4Ge8 cuboctahedra, faces with four equivalent HgGe12 cuboctahedra, and faces with fourteen equivalent GeHg4Ge8 cuboctahedra. All Ge–Ge bond lengths are 3.11 Å.
